The present invention also use the location and form of use of the insulating coating conductive mat for applying an AC high voltage is changed in the living body, to provide the alternating potential treatment device that can ensure the positive and negative peak value of the applied alternating current to a predetermined ratio. SOLUTION: A high end P1 of the secondary coil L2 in the AC step-up transformer T, while a series circuit of a diode D1 towards the high pressure end and the resistor R1, the protection combined divider B1 of the resistor R2 are connected in parallel as well as to connect the one end, the other end of the voltage divider circuit B1 and between the secondary coil ground terminal P2, and connect the positive voltage divider B2 the resistor R3 to the diode D2 connected in series to be directed to the ground terminal It is, to power the high voltage AC obtained from the divided voltage output end b between each of the voltage divider circuit B1 · B2 as a biological applied alternating current to the conductive mat m. Equivalent resistance value of the resistor R1 · R3, by setting the resistance value of the resistor R2 almost doubled, it is preferable that the positive and negative liquid high proportion of bio applied alternating current to one pair of three. .BACKGROUND【課題】生体に交流高電圧を印加する絶縁被覆導電マットの使用場所や使用形態が変化しても、印加交流の正負波高値を所定比率に確保できる交流電位治療器を提供する。【解決手段】交流昇圧トランスTにおける2次コイルL2の高圧端P1に、この高圧端に向けたダイオードD1と抵抗R1との直列回路に対し、抵抗R2を並列接続した保護兼用分圧回路B1の1端を接続すると共に、この分圧回路B1の他端と2次コイル接地端P2との間には、接地端に向けたダイオードD2に抵抗R3を直列接続した正電圧分圧回路B2を接続し、各分圧回路B1・B2間の分圧出力端bから得た高圧交流を導電マットmに生体印加交流として給電する。抵抗R1・R3の抵抗値を同等に、抵抗R2の抵抗値をほぼ2倍に設定して、生体印加交流の正負液高値比率を1対3にするのが好ましい。【選択図】図1
